+title: LEDs connected to TI TLC5925 controller

+
+description: |
+ The TLC5925 is a low-power 16-channel constant-current LED sink driver.
+ It is controlled through a SPI interface.
+ It is built around a shift register and latches which convert serial
+ input data into a parallel output. Several TLC5925 can be chained to
+ control more than 16 LEDs with a single chip-select.
+ The brightness level cannot be controlled, each LED is either on or off.
+
+ Each LED is represented as a sub-node of the ti,tlc5925 device.
